The inlet water channel, the first outlet water channel and the second outlet water channel are arranged inside the four-way joint. The water inlet channel, the first water outlet channel and the second water outlet channel are respectively communicated with the installation cavity. The water outlet end of the first water outlet channel is connected with a hand-held shower.

Further, the arm includes an arm body and a three-way body. The arm body is connected with the three-way body by a second screw rod and a second nut. The arm body is provided with a third outlet water channel. One end of the third outlet water channel is connected with the second outlet water channel. The other end of the third outlet water channel is connected with the three-way body. The outlet end of the three-way body is tapped for connecting with the top spray.

Further, a first pattern is arranged on an end surface of the four-way joint connected with the arm.

Further, the water outlet of the first water outlet channel is tapped with external threads for connecting the handheld shower.

Further, an end surface of the arm contacting with the four-way joint is provided with a second pattern.

Further, an inlet end of the inlet water channel of the four-way joint is tapped with a positive screw thread. The water inlet end of the water inlet channel is equipped with a spin tightening component. The spin tightening component comprises a lock nut and a lock joint. The lock nut is screw-connected with the water inlet end of the water inlet channel. The lock joint is internally provided with a reverse thread.

The present disclosure has the following advantages: (1) the shower arm of the present disclosure can be connected with the hand-held shower and the top spray at the same time, thus realizing the water discharge function of the shower and the top spray. (2) The shower arm of the present disclosure is simple in structure, an overall outfit is beautiful and the user experience is good. (3) In addition, the support arm of the disclosure has less lock structure and no angle displacement, rotation, loosening and the like aft continuous stress, and is reliable in use.

DETAILED DESCRIPTION OF THE EMBODIMENTS

As shown in the figures, a novel multi-functional shower support arm is disclosed. The support arm includes a handle 1, a locking cap 2, a switching valve 3, a four-way joint 4 and a support arm 5. An installation cavity 41 is defined in the four-way joint 4. In the mount cavity 41, the switching valve 3 is mount and fixed by the locking cap 2. The head of the switching valve 3 is connected with the handle 1. The four-way joint 4 is welded and connected with the first screw 6. The four-way joint 4 is connected with the arm 5 through the cooperation of the first screw 6 and the first nut 7, and the end of the arm 5 is connected with the top spray. The four-way joint 4 is internally provided with an inlet channel 42, a first outlet channel 43, and a second outlet channel 44. The inlet channel 42, the first outlet channel 43, and the second outlet channel 44 are respectively communicated with the installation cavity 41. The outlet end of the first outlet water channel 43 is connected to a shower head.

The arm 5 includes an arm body 51 and a three-way body 52. The three-way body 52 is connected to the arm main body 51 by a second screw 8 and a second nut 9. A third water discharge channel 511 is provided in the arm body 51. One end of the third water outlet channel 511 communicates with the second water outlet channel 44, and the other end communicates with the three-way body 52. The outlet end of the three-way body 52 is tapped with a screw for connecting the top spray.

The end surface of the four-way joint 4 connected to the arm 5 is provided with a first pattern 45.

The water outlet of the first water outlet channel 42 is externally threaded for connecting to a handheld shower.
